After the show, the 43-year-old comedian took to his Twitter and posted a comment on the surprise appearance, "we had a very very famous surprise walk-on guest tonight. my head is still spinning..." It wasn't until hours later that he joked about his man-on-man kiss. "legend has it that if @charliesheen kisses you at midnight, you turn into a whorewolf," so his tweet read.

Charlie crashes the "Jimmy Kimmel Live!" during an interview segment with guest Mark Cuban. When Jimmy asked Mark about his potential project with Charlie, the troubled star popped out on stage, high-fiving and blowing kisses to the audience before kissing Jimmy on the lips. After a lengthy lip-lock, he told the host, "Your lips are very moist."

During his surprise appearance, Charlie handed out several "Winning" and "tiger blood" T-shirts to the audience. He additionally gave Jimmy a mug and said, "It's got a fox on it." When asked to explain the meaning behind the fox before he exited the stage, the 45-year-old actor responded simply, "I'll let you figure it out, man."
